Another use case is coming from the services (e.g. Trove) which will create vms in the service tenant but using the resources (e.g. network or port) given by the non-admin user.

i believe this is intentional.

we do not currently allow you to trasfer ownerwhip of a vm form one user or proejct to another.
but i also believe we currently do not allow a vm to be create from resouces with different owners

That's not true. As the admin user, you are allowed to create a vm using non-admin's network, security group, image, volume, etc but just not port.

There is use case for admin user to create vms but using non-admin's resources for debugging or other purposes.

What's more, the exception is raised in nova-compute not nova-api, which i assume it should be supported if it's allowed in the api layer.
